Question

4(0,5x-3)-6(0,3x-4)=12,24

Answer 1

2х-12-1.8х+24=12.24
2х-1.8х=12.24-24+12
0.2х=0.24
х=0.24:0.2
х=1.2

Answer 2

4(0,5x-3)-6(0,3x-4)=12,24

2x-12-1.8x+24=12.24

0.2x+12=12.24

0.2x=12.24-12

0.2x=0.24

x=$\frac{6}{5}$

x= \frac{1}{5}

x=1.2

x=

Answer 3

To solve the equation 4(0.5x - 3) - 6(0.3x - 4) = 12.24, you can follow these steps:

1. Distribute the constants outside the parentheses into the expressions inside the parentheses:

   2(0.5x) - 2(3) - 6(0.3x) + 6(4) = 12.24

2. Simplify the expressions inside the parentheses:

   x - 6 - 1.8x + 24 = 12.24

3. Combine like terms:

   (x - 1.8x) + (24 - 6) = 12.24

   -0.8x + 18 = 12.24

4. Now, subtract 18 from both sides of the equation to isolate the variable x:

   -0.8x + 18 - 18 = 12.24 - 18

   -0.8x = -5.76

5. Finally, divide both sides by -0.8 to solve for x:

   (-0.8x) / (-0.8) = (-5.76) / (-0.8)

   x = 7.2

So, the solution to the equation is x = 7.2.
